A Windy City classic with an UpDog Hot Dogs twist! Our Chicago Dog features an all-beef hot dog nestled in our signature soft and buttery potato roll, then topped with yellow mustard, bright green relish, fresh chopped onions, juicy tomato slices, dill pickle slices, sport peppers, and a dash of celery salt—just like they do in Chicago! No ketchup, no compromises—just pure, mouthwatering flavor. *WARNING: Sport peppers are spicy!*
